Haemangioma of the ovary with associated endometrial hyperplasia. Case report

Ovarian haemangioma: A rare case report

“… 2,3,9 Preoperative Doppler examination of such a lesion may show a low-resistant vascular flow pattern, supporting malignant neoplasia of the ovary. Pseudo-Meigs’ syndrome, 2 stromal luteinization, stromal hyperplasia, 3,9–15 and thrombocytopenia have also been reported as complications of ovarian haemangioma. The decreased platelet count is regarded as one of the manifestations of Kasabach and Merritt syndrome, particularly in bilateral cases associated with diffuse abdominopelvic haemangiomatosis.…”

“… 11,13 According to another hypothesis, the presence of an expansile ovarian hemangioma induces stromal luteinization by mass effect. These luteinized stromal cells produce androgens, which are subsequently converted to estrogens in adipose tissue, potentially causing unopposed estrogenic stimulation to the endometrium which may present as postmenopausal or dysfunctional uterine bleeding, 3,11,12,14 aching breasts, 12 advanced male type hair loss, 3 and elevated androgen and estradiol levels. 3 …”

Papillary endothelial hyperplasia of adnexal vasculature

“…Vascular lesions including neoplasms are rare in the internal female genital tract. Reported adnexal vascular tumours include a histiocytoid (epithelioid) vascular tumour of ovary within a benign cystic teratoma 8 , an intravascular capillary haemangioma within the capsule of an ovarian serous cystadenoma 9 , an ovarian haemangiopericytoma 10 , and several ovarian haemangiomas [11][12][13] and angiosarcomas [14][15][16] . Occasionally, neoplasms such as cystic teratomas have prominent vascular components 17 .…”
